OVERVIEW
The channel strips are independent of each other, and allow you to adjust, tweak and otherwise beautify the sound coming from your different microphones, guitars and other in- struments. The Faders and Pans let you adjust how much of each channel is sent to the main mix. The Auxes let you adjust how much of each channel goes to your stage monitors or out to external or internal effects.
The channel strips come in two flavors: Mono and Stereo. In addition, the DFX•12 has two
16. GAIN
If you haven’t already, please read “SET THE LEVELS” on page 5.
The GAIN control adjusts the input sensitivity of the mic and line inputs on each channel. This allows signals from the outside world to be adjusted to optimal internal operating levels.
Through the mono channel MIC (XLR) in- puts, there is 50 dB of gain fully up. For stereo channel MIC inputs, this is +40 dB.
Through the mono channel LINE IN (TRS) inputs, there is 20 dB of attenuation fully down and +30 dB of gain fully up, with a “U” (unity gain) mark halfway up. The stereo channel LINE INs have a maximum gain of +20 dB.

2-BAND CHANNEL EQ
The DFX Mixers use “shelving” equalization. This boosts or cuts all frequencies past a specified frequency. For example, turning the LOW EQ (20) knob clockwise will boost the bass frequencies at 80 Hz and below.
Although you can bring sound to life with proper EQ, you can also mess things up. If you max the EQs on every channel, you’ll get mix mush, not to mention driving your mix levels near or beyond clipping. So equalize subtly; use cut as well as boost.
Adjusting the channel EQ will affect your main mix and the AUX 2/EFX (8) output, but not the AUX 1/MON (7) output.

After you connect a microphone or line-
level component to the mixer, do a sound test and adjust the GAIN (16) control until this handy LED flickers just occasionally. If it is glowing constantly, turn the GAIN down. If the LED is doing almost nothing, turn it up.
